The sum of two adjacent angles that make up a 90° angle is 90°. So, we have the equation:
x + (x+30) = 90
Combining like terms, we get:
2x + 30 = 90
Subtracting 30 from both sides, we get:
2x = 60
Dividing both sides by 2, we find:
x = 30
So, the value of x is 30.
For two adjacent angles with measures x° and (x+30)° that make up a 90° angle, what is x ?(1 point)
